Hopefully this e-mail's format doesn't get butchered too badly, but
here's a function that walks down a DOM tree looking for a Node with
specific attribute value:
/**
* startNode is the node to start searching from
* criteria is the attribute name
* value is the attribute value
*
** isIE is a global variable that says whether or not IE is being used.
** IE has non-standard ...
*/
NodeUtils.getNode = function (startNode, criteria, value) {
if (startNode.nodeType == Node.ELEMENT_NODE) {
var attr = null;
if (isIE && criteria == "class") {
// try class
attr = startNode.attributes["class"];
if (attr == null) {
// try className
attr = startNode.attributes["className"];
}
} else {
attr = startNode.attributes[criteria];
}
if (attr != null) {
if (isIE && startNode.nodeName == "FORM" && criteria == "name"){
if (startNode.attributes['name'].nodeValue == value) {
return startNode;
}
} else {
var attributes = attr.nodeValue.split(" ");
for (var i = 0; i < attributes.length; i++) {
if (attributes[i] == value) {
return startNode;
}
}
}
}
}
// Iterate children.
var children = startNode.childNodes;
for (var i = 0; i < children.length; i++) {
// Check this child node to see if it meets the criteria
var childSearch = NodeUtils.getNode(children[i], criteria, value);
if (childSearch != null) {
return childSearch;
}
}
}
So, with this function you could do something like:
var myForm = NodeUtils.getNode(document.documentElement, "name",
"myForm");
or
var myForm = NodeUtils.getNode(document.getElementById("formDiv"),
"name", "myForm");
